제목 Superior Antifouling Properties of Bioinspired Ambivalent Block Copolyethers
초록 PEG has attracted significant interest because of its excellent antifouling properties and high solubility and biocompatibility. However, the translation of its antifouling properties onto target surfaces has been challenging due to its limited functionality. Herein, we studied the antifouling properties of loop-like triblock copolyethers functionalized with catechol, a mussel-inspired, versatile moiety for coating, exclusively within a framework of polyethers. A series of catechol-functionalized polyethers with diverse molecular weights and catechol contents were synthesized via anionic ring-opening polymerization in a controlled manner. The versatile adsorption and antifouling effects of ambivalent block copolyethers were evaluated using a QCM-D. Furthermore, the crucial effects of the topology in the antifouling properties was analyzed via an SFA and MD simulations. This result demonstrates the catechol-functionalized triblock copolymer shows excellent antifouling properties.
